The Lapidarium - a collection of stone monuments from the Roman period in the form of an archaeological park in the Museum courtyard is open every day.

Stone monuments from the Greek and Roman periods, of varied purpose and content, represent one of the more important segments of the rich classical collections of the Archaeological Museum. The wide selection of Roman stone monuments, organized into several thematic units, is exhibited partly in the ground level entrance to the museum, but primarily in the garden courtyard of the museum, both under modern arcades and in the open air. Various stone monuments of large dimensions and weight, such as milestones, inscriptions, monumental statues, altars, tombstones, sarcophagi, and others, are exhibited here.
